- Bring the README's platform, comparator and overhead claims up to date
- Let check compare two arbitrary refs
check took one ref and always compared it against the working tree, so
reviewing someone else's branch or auditing a release meant checking it out
first. A second optional positional ref is now the candidate:
nodrift check HEAD~1 HEAD
With no second ref the working tree is still the candidate, which is the
common case.
Closes #11
A repository with __pycache__ committed hands the replay bytecode compiled from other source. Python runs it in preference to the file git archive just materialised, so both versions behave identically and check reports no behaviour change while the code genuinely differs. Found while testing two-ref comparison: a tree staged from a commit containing POSITIVE replayed as positive, and check called it clean. The one-ref path had the same hole. Silent wrongness rather than an error, which is the worst failure this tool has. Compiled artifacts are now removed from every staged tree, exported or copied. The regression test commits stale bytecode deliberately and fails without the fix.
